Promoting a Cobalt Complex of Qingzhuan Dark Tea Polysaccharides on Fracture Healing in Rats

Fractures occur commonly with multiple injuries, and their incidence has increased in recent years. Trace amounts of cobalt are necessary for many living organisms as it stimulates hematopoiesis and improves bone health. However, cobalt is also toxic, as it might cause allergic reactions and tissue destruction. These factors limit the application of cobalt in some medical fields. We studied the tea polysaccode-cobalt complex (TPS-Co) prepared from Qingzhuan Dark Tea polysaccharides. We used 6-week-old Sprague-Dawley rats to establish a femoral fracture model and evaluated the effects of CoCl2 and TPS-Co on the healing of femoral fractures. In this study, treatment with TPS-Co for the same content of cobalt intake decreased the side effects associated with CoCl2 treatment and accelerated the healing of femoral fractures in rats. This treatment method promoted angiogenesis by upregulating the expression of vascular endothelial growth factor and hypoxia-inducible factor. Bone formation was promoted via the upregulation of the expression of bone morphogenetic protein 2 and serum bone alkaline phosphatase. TPS-Co was found to actively regulate bone and vascular systems, resulting in significant bone regeneration effects. Therefore, the Qingzhuan Dark Tea polysaccharide cobalt complex might be used as an additive or drug to promote fracture healing, and thus, it might have a huge market value.

Treatment of Mandibular Impacted Canine in a Patient with Class II Division 1 Malocclusion with "Reverse Pin": A Case Report

This case report presents an orthodontic treatment conducted on a 13-year-old girl with bilateral Class II malocclusion and a mandibular impacted canine. The presence of an impacted tooth necessitates careful consideration of the timing of orthodontic treatment, the appropriate surgical procedure to expose the tooth, the specific orthodontic mechanics involved, and the potential problems that may arise, all of which depend on the type and location of the canine impaction in the jaw. The treatment plan included a surgical procedure to expose the impacted tooth and orthodontic traction to guide it into position. Correction of the Class II Division 1 malocclusion utilized a specialized technique called the "reverse pin", reducing vertical side effects. The revised version maintains clarity and key information about the case report and treatment.

Mothers' knowledge, practice, and attitudes toward vitamin D deficiency among children in the Qassim region, Kingdom of Saudi Arabia

Vitamin D comes in two forms: ergocalciferol (D2) and cholecalciferol (D3). This study aimed to assess mothers' knowledge, attitudes, and practices toward vitamin D deficiency among children. We collected data using a self-administered online questionnaire to gather information about the characteristics, knowledge, attitudes, and reported practices of 800 Saudi Arabian mothers regarding vitamin D deficiency. The mean age of participants was 31.2±4.76, and 8% had a university education. When it came to household income, the majority (90.1%) reported that they had enough money. Participants who attended training courses, employed mothers, total practice, and total attitude had a significant favorable effect on knowledge, with a p-value of less than 0.01. Employed mothers, training course attendees, total practice, and overall attitude had a significant favorable effect on mothers' practice, with a p-value of less than 0.01**. More than half of the mothers who participated in the study had an inadequate level of understanding. Less than two-thirds of those surveyed noted the deficient practice. Two-thirds of the moms who participated in the study had a negative attitude toward vitamin D deficiency. There was a strong positive correlation between total knowledge, total attitude, and total practice-related vitamin D deficiency.

From Bench to Bedside in Precision Medicine: Diabetes Mellitus and Peri-Implantitis Clinical Indices with a Short-Term Follow-Up: A Systematic Review and Meta-Analysis

Background and objective: Diabetes mellitus (DM) refers to a group of metabolic disorders characterized by hyperglycemia resulting from impaired secretion or action of insulin. The high levels of glucose in the blood can negatively affect the healing processes through alterations in vascularization, bone remodeling, and with increased susceptibility to infections. Diabetes mellitus is therefore a risk factor not only for many systemic diseases, but also for localized problems such as peri-implantitis. The objective of this systematic review was to identify a clear relationship between peri-implant inflammation indices and glycemic levels, through the investigation of prospective studies that report data on a short-term follow-up period. Our hypothesis was that peri-implant inflammatory indices may already present themselves in a statistically significant way as altered in patients with DM compared to patients without DM. Materials and methods: This review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Results: More than 992 records were identified in the PubMed, Scopus, and Cochrane Central Register of Controlled Trial electronic databases and only seven studies were included in the meta-analysis. The results of the meta-analysis report worse outcomes in patients with DM, even in the short period of six months, for peri-implatitis inflammation indices, such as Marginal bone loss (standardized (Std). mean difference (MD) 12\6 months 0.81 [0.45, 1.17]\1.82 [0.53, 3.10]), Bleeding on probing (Std. MD 12\6 months 2.84 [1.34, 4.34]\3.44 [1.41, 5.50]), Probing depth (Std. MD 12\6 months 1.14 [0.60, 1.68]\2.24 [0.66, 3.83]), and the plaque index (Std. MD 12 months 2.83 [0.09, 5.57]). Conclusion: The literature linking glycaemic control to peri-implant disease is highly heterogeneous due to lack of consistency of the definition of peri-implantitis and its clinical indicators among studies. Therefore, interpretation of finding and relevance to clinical practice should be considered on individual bases. In the era of personalized medicine, the clinician should utilize individualized information from translational researches and analyze all risk factors to provide the patient with evidence-based treatment options.

Efficacy of a Non-addictive Nasal Irrigation Based on Sea Salt Enriched with Natural Enzymes among Patients with Sinusitis: An In Vivo, Randomized, Controlled Trial

BACKGROUND: Chronic rhinosinusitis (CRS) is a common condition that is defined as inflammation of the nose and paranasal sinuses. Nasal irrigation plays an important role in the treatment of CRS. Evidence from basic research favors hypertonic saline over isotonic saline for mucociliary clearance, but evidence from clinical studies is controversial. AIM: This study aims to investigate the hypothesis that the use of daily nasal irrigation based on sea salt, enriched with natural enzymes and lysozyme, may be useful in patients with CRS. PATIENT AND METHODS: Patients (30 men and 30 women) 18–55 years old (mean age 41 ± 3 y.o.), with two episodes of acute sinusitis or one episode of chronic sinusitis per year for 2 consecutive years, were enrolled stratified by sex and age and randomly divided into two groups supplementation: Group A (test) and Group B (control/placebo). Moreover, an exit questionnaire was asked to Group A subjects to report whether their sinus-related quality of life has gotten worse, stayed the same, or improved (scale from 0 to ±100%). RESULTS: The result showed that in the test group (A) from T0 to T1, a reduction of 17.65% for the symptoms related headache and/or facial pressure and a reduction of the 18.18%, for the symptoms relates to congestion and/or nasal discharge. On the other hand, the control group (B) shown less difference between T0 and T1. CONCLUSIONS: This study strengthens the argument that the tested formulation is a safe, well-tolerated, long-term therapy that patients with chronic sinonasal complaints can and will use at home with minimal training and follow-up.

Non-linear relationship between albumin-corrected calcium and 30-day in-hospital mortality in ICU patients: A multicenter retrospective cohort study

OBJECTIVE

Albumin-corrected calcium is usually calculated to reflect the real serum calcium level of the whole body by physicians. However, studies on the association between albumin-corrected calcium and 30-day in-hospital mortality in Intensive Care Unit (ICU) patients are rare. The purpose of our study was to explore the association between baseline albumin-corrected calcium and 30-day in-hospital mortality in the American ICU population.

METHODS

A multicenter retrospective cohort study of 102,245 ICU patients in the eICU-CRD v2.0 from the USA during 2014-2015 was performed. The average age was 63.7 ± 16.9 years, of which 55,313 (53.7%) were men and 47,758 (46.3%) were women. The association between albumin-corrected calcium and 30-day in-hospital mortality was analyzed by Cox proportional-hazards regression, smooth curve fitting, piecewise linear regression, subgroup analyses, and a series of sensitivity analyses.

RESULTS

We found that among ICU patients with calcium abnormalities, more than 95% were mild hypocalcemia or mild hypercalcemia. The risk of 30-day in-hospital mortality will increase by 10% in the ≥7.5-< 8.5 mg/dl subgroup (OR=1.1, 95% CI 1.0-1.3) or 20% in the ≥10.3-<12 mg/dl subgroup (OR=1.2, 95% CI 1.1-1.3) when the albumin-corrected calcium level increases by 1 mg/dl. Additionally, the relationship between albumin-corrected calcium and 30-day in-hospital mortality was U shaped; the inflection point was 8.9 mg/dl (log likelihood ratio test P = 0.005). Finally, after a series of sensitivity analyses, we found that the relationship between albumin-corrected calcium and 30-day in-hospital mortality remained significant.

CONCLUSION

In a large nationally representative cohort of ICU patients, abnormalities in albumin-corrected calcium, particularly slight hypocalcemia or slight hypercalcemia, were associated with an increased 30-day in-hospital mortality risk, and yet the findings in this study need to be further confirmed by prospective studies.

Efficacy of bio-activated anti-calculus toothpaste on oral health: a single-blind, parallel-group clinical study

BACKGROUND

Current epidemiologic studies have confirmed the widespread presence of calculus in teenagers and adults of all ages. Among the multiple anti-calculus strategies that have been proposed over the years inhibition of crystal growth has been the most attractive. Current formulations in anti-calculus toothpastes and mothwash, utilise either hydroxyapatite or various pyrophosphate combinations. This study aimed to analyze the efficacy of an anti-calculus tooth paste in combination or not with a mouth rinse.

PATIENTS AND METHODS

Patients (totally 40) used a pyrophosphate-based toothpaste containing Tetrapotassium Pyrophosphate, Pentasodium Triphosphate, Xylitol, Hydroxyapatite, Citric Acid, And Calcium Carbonate (Group A) in combination, with a mouth rinse containing an association of Pentasodium Triphosphate, Tetrapotassium Pyrophosphate and Citric Acid (Group B). A range of parameters were measured for: saliva pH, Volpe Manhold Calculus Index (VMI), Gingival Index (GI), and Plaque Index (PI).

RESULTS

The test mouth rinse Group B showd reductions in VMI, GI, PI, and increases in pH levels, after using the combination of toothpaste and mouth rinse. No changes to the mucosa or teeth were observed in both Groups. Patients perceived that the comitation of products was more effective.

CONCLUSIONS

The results from the three-month calculus examination indicated that both the tested products, modified positively clincal parameters and salivary pH. Moreover, the use of the tested products was not associated with any adverse effects.

Review on Surface Treatment for Implant Infection via Gentamicin and Antibiotic Releasing Coatings

Surface treatment of metallic implants plays a crucial role in orthopedics and orthodontics. Metallic implants produce side-effects such as physical, chemical/electro-chemical irritations, oligodynamic/catalytic and carcinogenic effects. These effects cause bacterial infections and account for huge medical expenses. Treatment for these infections comprises repeated radical debridement, replacement of the implant device and intravenous or oral injection antibiotics. Infection is due to the presence of bacteria in the patient or the surrounding environment. The antibiotic-based medication prevents prophylaxis against bacterial colonization, which is an emphatic method that may otherwise be catastrophic to a patient. Therefore, preventive measures are essential. A coating process was developed with its drug infusion and effect opposing biofilms. Modification in the medical implant surface reduces the adhesion of bacterial and biofilms, the reason behind bacterial attachment. Other polymer-based and nanoparticle-based carriers are used to resolve implant infections. Therefore, using an implant coating is a better approach to prevent infection due to biofilm.
